Extensions.XPathSelectElements Method (XNode, String)

public static IEnumerable<XElement> XPathSelectElements(
	this XNode node,
	string expression
)

Usage Note

Although the ordering of returned collections is not specified in the XML XPath Language 1.0 Recommendation, this extension method returns nodes in document order.

Note that nodes are returned in document order even when you use a reverse axis, such as preceding-sibling or ancestor-or-self.

The following example creates a small XML tree and uses XPathSelectElements to select a set of elements.

XElement root = new XElement("Root",
    new XElement("Child1", 1),
    new XElement("Child1", 2),
    new XElement("Child1", 3),
    new XElement("Child2", 4),
    new XElement("Child2", 5),
    new XElement("Child2", 6)
);
IEnumerable<XElement> list = root.XPathSelectElements("./Child2");
foreach (XElement el in list)
    Console.WriteLine(el);

This example produces the following output:

<Child2>4</Child2>
<Child2>5</Child2>
<Child2>6</Child2>
